The confluence of the Colorado and Little Colorado rivers in the Grand Canyon, shown here in a September 2020 aerial photo from Ecoflight, represents an area where the humpback chub has rebounded in the last decade. That progress is now threatened by declining water levels in Lake Powell, which could lead to non-native smallmouth bass becoming established in the canyon. CREDIT: JANE PARGITER/ECOFLIGHT
